Computer-implemented systems and methods for optimizing sorting and loading of packages are disclosed. An exemplary system includes a memory storing instructions and may include at least one processor configured to execute the instructions. The system may perform operations including receiving data comprising a plurality of package identifiers associated with a plurality of packages. The operations may include determining a plurality of block areas associated with delivery locations for the plurality of packages. The operations may further include determining a delivery route by determining a first set of routes, determining optimal combinations of the inputs for each set of routes and determining a shortest route associated with the optimal combinations. The operations may include determining an order in which to load each of the packages into a delivery vehicle. The operations may further include generating instructions for causing a device to display a visual representation of the loading order.

Systems, methods, and devices for designating a location for a delivery item that is being sorted by an operator. The operator scans the delivery address of the item using a scanner having a particular attribute, such as being painted red. Using delivery address along with an identifier for the scanner that was used, the system determines a sort output location for the item, identifies a designator (e.g. a specific color, such as red) that corresponds to the scanner, and identifies an indicator device (e.g., a multicolor LED device) that corresponds to the sort output location. The system then commands the indicator device to present or display the designator. For example, the indicator device may be commanded to illuminate a LED to give off red light. The operator of the red scanner then places the item at the location corresponding to the red light designator.

In order to detect a correct sorting and a correct passing of an object through an assigned opening of a plurality of openings, a sorting detection system for detecting a passage of the object through the opening of the plurality of openings is provided. Each opening is assigned to a container. The containers receive the object; at least a first sensor identifies the object and generates an identification signal. A control unit receives the identification signal of the first sensor and assigns the identified object to a container based on the identification signal. At least one second sensor having a field of view directed towards the openings and includes at least one detection surface. The detection surface is located within the respective container at a predetermined distance from an edge of a respective opening, and an object passing the detection surface triggers a detection signal of the second sensor.

There is provided a projection instruction device that generates a projection image to be projected on a parcel based on a reading result of parcel identification information included in a label attached to the parcel, the device including: a processor; and a memory, in which by cooperating with the memory, the processor detects occurrence of an error, and moves the parcel to upstream in a case where the occurrence of the error is detected.

There is provided a projection instruction device that generates a projection image to be projected on a parcel based on parcel identification information specifying the parcel, the device including: a processor; and a memory, in which by cooperating with the memory, the processor specifies a person in charge of processing the parcel or a destination of the parcel based on the parcel identification information to generate a person in charge instruction projection image indicating at least one of the person in charge or the destination of the parcel.

There is provided a parcel recognition device that recognizes a parcel based on an image including the parcel, the device including: a processor; and a memory, in which by cooperating with the memory, the processor recognizes a person in a recognition target space in the image, subtracts a space within a predetermined range including at least a part of the recognized person from the recognition target space, and recognizes the parcel by using a space obtained by the subtraction as a new recognition target space.

There is provided a parcel sorting system including: a transport conveyor; a sensor that obtains a distance image of a parcel passing through a sensing region including a part of the transport conveyor; and a projection instruction device that generates a projection image to be projected on the parcel based on the distance image, in which the transport conveyor includes a parcel separation unit that separates adjacent parcels, inside the sensing region.

There is provided a parcel recognition device that recognizes a parcel based on a color image including the parcel, the device including: a processor; and a memory, in which by cooperating with the memory, the processor subtracts a color of a projection image from a color of an image projection surface of the parcel on which the projection image is projected, in the color image, and sets a color obtained by the subtraction as a color of a recognition target, and recognizes the parcel.

There is provided a projection instruction device that generates a projection image to be projected on parcel based on sensing information of the parcel, the device including: a processor; and a memory, in which by cooperating with the memory, the processor performs weighting on a value of a feature amount of a color image of parcel included in the sensing information based on a distance image of parcel included in the sensing information, and tracks the parcel based on the weighted value of the feature amount of the color image.

There is provided a parcel determination device that determines whether or not parcel recognized in a first recognition region provided in a predetermined transport path and parcel recognized in a second recognition region being disposed on a downstream side from the first recognition region in the transport path and being discontinuous with the first recognition region are the same parcel, the device including: a processor; and a memory, in which by cooperating with the memory, the processor determines whether or not parcel which leaves the first recognition region and parcel which enters the second recognition region are the same parcel, based on whether or not a time when parcel leaves the first recognition region and a time when parcel enters the second recognition region correspond to a time required for parcel to be transported between the two recognition regions.
